Rev. 2.0
Nov. 11, 1998
Description
The HM62W1400H is a 4-Mbit high speed static RAM organized 4-Mword × 1-bit. It has realized high
speed access time by employing CMOS process (4-transistor + 2-poly resistor memory cell)and high speed
circuit designing technology. It is most appropriate for the application which requires high speed and high
density memory, such as cache and buffer memory in system. The HM62W1400H is packaged in 400-mil
32-pin SOJ and 400-mil 32-pin TSOP II for high density surface mounting.

Note:
Notes
1. Transition is measured ±200 mV from steady voltage with Load (B). This parameter is sampled
and not 100% tested.
2. Address should be valid prior to or coincident with CS transition low.
3. WE and/or CS must be high during address transition time.
4. if CS and OE are low during this period, Dout pins are in the output state. Then, the data input
signals of opposite phase to the outputs must not be applied to them.
5. If the CS low transition occurs simultaneously with the WE low transition or after the WE transition,
output remains a high impedance state.
6. t AS is measured from the latest address transition to the later of CS or WE going low.
7. t WR is measured from the earlier of CS or WE going high to the first address transition.
8. A write occurs during the overlap of a low CS and a low WE. A write begins at the latest transition
among CS going low and WE going low. A write ends at the earliest transition among CS going
high and WE going high. tWP is measured from the beginnig of write to the end of write.
9. t CW is measured from the later of CS going low to the the end of write.
